I have a 91 S10 2.8l 5sp. I'm wanting to do the 3.4 swap. I'm wanting to keep a manual transmission. Will this swap work with the stock 5sp or will I need a different one? Also is there a thread that talks about the other parts I will need to do this? I am not a mechanic but want to learn so will be paying someone to guide me through it when I do the swap. Any help is appreciated.

Remove your 2.8. Attach 3.4 to your trans. Put it back in. Swap injectors to 4.3. Drive. That simple on 91. You’ll need to do some tuning or have someone do it for you for best performance.

Yea, the only way you'd run into trouble is trying to use a FWD 3.4L, then you'd need a bellhousing from a 94-95 2.2L since it has the starter on the driver's side.

Along with a bunch of other, mostly custom parts and work...
